SPOOL-HOLDER FOR BRAlDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 638,059, dated November 28, 1899.

Application filed August 19, 1899. Serial No. 727,740. (No model.)

To all whom it may concern.-

Be it known that I, EWALD MUNDT, a citizen of the United States, residing in the city of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Spool-Holders for Braiding-Machineaof which the following is a specification.

This invention relates to certain improve ported on the spindle that it can be readily removed from the holder and replaced therein with great facility.

The invention consists of a spool-holder for braiding-machines, which comprises a spindle on which the spool rotates, a guard attached to the base of the spoolholder, a locking-latch hinged to the upper end of the guard and provided with means for receiving the spindle, a disk applied to the latch and provided with a stop-pin for engaging the upper end of the spool and limiting the upward motion of the same, and means for interlocking 3 5 the latch with the guide-box for the tensionweight.

The invention consists, further, of a spoolholder provided with an upright guide-box of polygonal cross-section, a tension-weight guided in said box and made of corresponding section, and a pawl guided in the upper end of the guide-box and adapted to engage the ratchet at the upper end of the spool, so as to intermittently release the same for feed- 5 ing the thread; and the invention consists,

further, of certain details of construction, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved spool-holder for braiding-machines. Fig. 2

is a side elevation looking toward the guidebox. Fig. 3 is a plan view of Fig. 1, drawn on a larger scale. Fig. 4 is a detail vertical section of the upper part of the spool-holder, drawn on a larger scale, so as to show the operative parts; and Fig. 5 is a horizontal section on line 5 5, Fig. 4.

Similar letters of reference indicate corresponding parts. I

Referring to the drawings, A represents a spool on which the braid-forming thread is wound, and C a spindle which is mounted on a racer F, that is provided with top and bottom plates F F and a vertical web F between the same, which web serves to guide the spoolholder in the serpentine grooves of the racerplate of the machine. To the top plate F of the racer is attached an upright guide-box B, which is made of polygonal cross-section and which serves as a guide for the tension-weight B of the thread. The tension-weight B is made also polygonal in cross-section, so as to prevent the turning of the weight and the shifting of its position in the guide-box. On the lower partof the spindle U is mounted a disk D, which serves as a support for the spool A.

Partly encircling the spool-holder and concentric with the axis of the spindle O is arranged a segmental guard-plate G, which is attached to the disk D and is made of suitable sheet metal. The upper end of the spool A is provided in the usual manner with ratchetteeth a, which are engaged by the tooth 19 of a pawl 19, that is pivoted at one end to the under side of a disk-shaped cap-plate G, which has a hinge connection with the upper end of the guard G. The end p of the weighted pawl 19 projects through slot 1) in the guide-box and is intermittently lifted by the tension-weight B, so that its tooth 19 is removed from the ratchet-teeth a of the spool A to permit the turning of the latter and thesupply of thread to the braid being made on the machine.

The threadt is guided from the spool around the outer surface of the guardplate G through an eye 25, through an eye 25 of a sleeve i fixed on the guide-box, through a hole 0 in the upright guide-box B, then through the tension- I00 eye 1) of the weight B, and, lastly, through a tension-eye e in the locking-latch E, which carries the cap-plate G, said locking-latch connecting the upper end of the guard-plate G with the upper end of the guide-box B.

The cap-plate G and latch E are provided with an opening for receiving the end of the spindle O,said spindle being held in stationary position, so as to permit the spool to rotate freely thereon.

The locking-latch E is clearly shown in Figs. 3 and 4 and is provided with an angular hook E at its outer end, that engages a projection c at the upperend of the guide-box. The guideboX is provided with upwardly-proj ectin glu gs e at the sides,which serve to retain the end of the latch against lateral displacement when the hook of the same engages the projection e. The yielding upper end of the guide-box B gives sufficient spring so as to retain the latch firmly in position, it being opened whenever the spool is to be removed by pressing the guide-box inwardly and releasing the latch, which swings, with the hinged cap-plate G, on the upper end of the guard-plate G.

The pawl 19 is provided with an elongated opening for permitting the passage therethrough of the spindle and its free movement without interference by the spindle.

To the cap-plate G is attached a downwardly-extending pin 9, which engages the upper end of the spool inside of the ratchetteeth e and which serves to prevent the up-' and-down play of the spool in following the tension of the thread in the unwinding motion of the same. This pin gserves as a stop for arresting the upward motion of the spool and retaining the same reliably in its proper position on the spindle.

The new features of my improved spoolholder are the improved construction of the locking-latch at the upper end of the holder, the arrangement of the st0ppin on the capplate of the same, and the guide-box for the tension-Weight. These new features have the advantages that the spool can be readily removed from the holder for replacing a new spool on the same; also, that the spool is retained in position in the holder and its upand-down play prevented, and, lastly, that the tension-weight is incased so that it does not discolor the thread by rubbing on the same, especially when threads of light color are used, which discoloration has been found to be an objectionable feature to uncovered tension weights guided on upright guidestandards of the spool-holder.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a spool-holder forbraiding-machines, the combination of a spindle, a spool suitably supported upon said spindle, a guard at one side of the spool, a latch hinged to the upper end of the guard, a guide-box for the tensionweight, and means for locking the latch to the upper end of said guide-box, substantially as set forth.

2. In a spool-holderfor braiding-machines, the combination of a spindle, a disk on the lower end of said spindle, a spool supported on said disk, a guard attached to said disk and extending alongside the spindle, an upright guide-box, a latch hinged to the upper end of the spindle, and means forlocking the latch to the upper end of the guide-box, substantially as set forth.

3. In a spool-holder for braiding-machines, the combination of a spindle, a spool suitably supported upon said spindle, a guard attached to said disk and extending alongside the spool, a latch hinged to the upper end of the guard and adapted to engage the guide of the tension-weight, and a cap-plate attached to said latch and provided with a stop-pin for engaging the spool, substantially as set forth.

4. In a spool-holder for braiding-machines, the combination of a spindle, a spool supported on said spindle and provided with ratchet-teeth, a guard at one side of the spool, an upright guide-box, a tension-Weight in said guide-box, a latch hinged to the upper end of the guard and adapted to interlock with the upper end of the guide-box, and a pawl hinged to the latch and adapted to engage the ratchet-teeth of the spool, the end of the pawl extending into the guide-box, so as to be acted on by the said weight, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
